The 'LVTH16244A devices are 16-bit buffers and line drivers designed for low-voltage
(3.3-V) VCC operation, but with the capability to provide a TTL interface to
a 5-V system environment. These devices can be used as four 4-bit buffers, two 8-bit buffers, or
one 16-bit buffer. These devices provide true outputs and symmetrical active-low output-enable
(OE) inputs.

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of
pullup or pulldown resistors with the bus-hold circuitry is not recommended.

When VCC is between 0 and 1.5 V, the devices are in the
high-impedance state during power up or power down. However, to ensure the high-impedance state
above 1.5 V, OE should be tied to VCC through a
pullup resistor; the minimum value of the resistor is determined by the current-sinking capability
of the driver.

These devices are fully specified for hot-insertion applications using
Ioff and power-up 3-state. The Ioff circuitry
disables the outputs, preventing damaging current backflow through the devices when they are
powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during
power up and power down, which prevents driver conflict.
